* elf32-i386.c (GOT_TLS_MASK, GOT_TLS_IE_IE, GOT_TLS_IE_GD, GOT_TLS_IE_MASK, elf_i386_check_relocs, allocate_dynrelocs): Revert 2006-04-08 changes. (elf_i386_relocate_section): Likewise. For GD->IE transition change subl into addl whenever tls_type is GOT_TLS_IE_POS. * ld-i386/tlsbin.dd: Fix expected output.
